SURGICAL INSTRUMENT.

Specification of Letters Patent.

Patented'Sept. 26, 1916.

Application filed May 10, 1916. Serial No. 96,575.

To all whom it may concern:

' Be it known that I, GIuLIo BACOLINI, a

subject of the King of Italy, and a resident of the city of New York, borough of Brooklyn, in the county of Kingsand State of New York, have invented a new and Improved Surgical Instrument, of which the following is a full, clear, and exact description.

My invention relates to surgical instruments particularly adaptable for manipulating the clips applied to incisions.

The object thereof is to provide .an instrument which will automatically feed the clips to the plying ends of the instrument after each manipulation of said plying ends.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indlcate corresponding parts in all the views.

Figure 1 is a top plan view of my instru ment; Fig. 2 is a longitudinal section on line 22 Fig. 1; Fig. 3 is a bottom-side-up .plan view of the instrument; Fig. 4: is a plan view of the clip carrier and feeder in position before it is placed into the instrument support;

,Fig. 5 is a transverse section on line 5-5,

Fig. 1; Fig. 6 is a similar view showing the plier ends forced against the chp; and Fig. 7 is a perspective view of the clip used in connection with the instrument.

Referring to the drawings, 8 is a longitudinal channeled member the longitudinal edges of which are turned inwardly to form flanges 9 which'prevent the dropping away of a slide 10 provided within the channeled member 8. The-slide is introduced into the channeled member through the rear end thereof. A block 11 plugs the rear end of the member 8. The block is locked to the member by a set screw 12. The block carries a pair of parallelly-spaced rods 13 which extend through the'entire length of the member 8. The distance between said rods is equal to the distance between. the eyelets of the clip 14; and the distance between the flanges 9 to the bottom of the channeled member 8 is sufficient to easily accommodate prongs 15 at the eyelets of the clips. The slide 10 has which the rods 13 pass.

A coil spring 16 is provided on each rod between the slide and the block 11, said openings through spring normally forcing the slide away from the block 11 toward the forward end of the member 8. The clips 14 carried by the rod in front of the slide will be'fed by the slide toward the forward end of the member 8. At-the forward end the member 8 is provided with a lip 17 rising above the bottom and forming an abutment for the clips. The sides of the member 8 at the lip are cut away to clear the way for the clipping ends 18 of the clamping tool 19 mounted on the upper surface of the member 8. The handles of the tool are engaged by a spring 20 which normally maintains'the slipping ends apart or clear of the ends of the clip abutting against the lip 17, the spreading of the clipping ends being limited by pins 21 pro vided on the member 8 (see Fig. 1).

The bottom of the member 8 at the forward end is partly cut out, as shown at 22, to expose the clip abutting against the lip and to permit said clip to bulge therethrough when the same is clamped by the clipping ends of the clamping tool (see Fig. 6). The ends of the rods 13 clear the lip 17 through a distance more than the width of a. clip, as best shown in Fig. 3.

the forward end of the tool, as shown best 1n Figs. 2 and 3, to facilitate the engagement of the clips with the incision to be sary to remove the block 11. To prevent the spring from forcing the slide 10 off the rods, said slide is provided with a hooked extension 23 directed toward the block. The block in turn has a depressible hooked extension 24 extending toward the slide and cooperating with the hooked extension 23.

The slide 10 has a milled head 25 above the flanges9 for bringing the hooked extension 28 into engagement with the hooked exten- The sides and the v flanges 9 of the member 8 are rounded near sion 24 of the block 11. The engagement of the two hooked extensions prevent the springs 16 from forcing the slide toward the ends of the rod. By removing the set screw 12 the block 11 may be removed from the member 8 and therewith the slide 11 which is. locked to the block. Clips can then be fed "on to the rods 13 against the slide 9 thereupon. See Fig. 4. 7

When the rods above the slide are covered by the clips, the rods with the clips are entered through the rear end of the member 8 and the block 11 is locked in position by the v screw 12. To release the slide and allow the lip 1 s 16 to bring the clips 14 against the depressible hooked end 24: must be depressed; and for that purpose the hooked extension 24 is provided with a projection 26 rising'above the flanges. When the hooked end isldepressed the hooked extension 24 disengages fromthe hooked extension 23 and the spring 16 will force the slide towardvthe forward end of the. tool, bringing the'clips' against the lip 17 The member8, which constitutes the sup port of the clamping tool and the clip feed, also serves as 'a'holder of the instrument, particularly the portion thereof beyond the handle of the clamping tool which are retained by the smaller fingers of the'hand in the manipulation of the instrument. The block 11, rods 13, springs 16, slide 9 and the the sprin hooked extension of the slide and the block constitute an automatic feed of the instrument and also the clip carrier. a

While I have described the principle of operation, togetherp'with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the appended claims.

I claim:

1. In a surgical instrument of the class described, a channeled support presenting a lip at one end thereof, a block locked to the other end of the support, parallelly-spaced rods extending from the block to the lip and terminating in close proximity to the lip, a slide within the support engaging the rods, springs on the rods between the block and the slide, said spring normally tending to move the slide toward the lip, the portion of the rods lying between the lips and the slides being adapted to carry clips, a clamp on said support having ends for plying clips at the lip, said channeled support being cut out in the bottom at the lip to allow the clips to buckle when collapsed by the clam and means for securing the slide to-the bloc whereby the springs on the rods are prevented from forcing the slide away from the.

block.

2. In a surgical instrument of the class described, a channeled support presenting a lip at one end thereof, a block locked to the other end of the support, parallelly-spaced rods extending from the block to the lip and terminating in close proximity to said lip, clips having eyelets adapted to be threaded on said rods, a slide engaging said rods, springs on said rods normally tending to move the slide away from the block whereby the clips threaded on the rods are moved by the slide toward the lip, said lip forming an abutment for the adjacent clip, a clamping tool secured to the support, said clamping tool having plying ends, said channeled support having the sides thereof cut away at the lips to clear the ath for the plying ends of the clamping too whereby a clip at the lip may be collapsed, said channeled support having a portion of its bottom at the lip cut out to-allow the clip collapsed by the plying ends of the tool to buckle therethr'ough and means for lockingthe slide to the block, substantially as and for,

the purpose set forth.

3. In combination with clips having eyelets at the ends thereof, a pair of spaced rods adapted to be threaded through the eyelets of the clips, a support adapted to accommodate said rods, a slide carried by the rods, springs on said rods engaging the slide to feed the clips off the rods, said support 'ment comprising an automatlc clip feed presenting rods adapted to thread the eyelets of the clips, a support for the automatic feed presenting an abutting lip against which the clips are fed, and a clamping tool for collapsing the clips at the lip, said support having a cut-out portion to allow acllp to bulge through the cut-out when collapsed by the clamping tool.
